Description

Technical Field

[0001] The utility model belongs to the technical field of concrete, and particularly relates to a concrete wall anti-cracking structure. Background Art

[0002] When pouring a concrete wall, first, the concrete formwork needs to be stably supported, and then the pouring can be carried out; the quality of the concrete wall depends to a large extent on the reliability of the formwork support system. The function of the formwork support system is not only to provide the shape and structure during concrete pouring, but more importantly, it ensures the uniformity and stability of the concrete during the hardening process. If the formwork support is unstable, the concrete may undergo uneven shrinkage during the hardening process, resulting in cracks. These cracks may form on the wall surface or be hidden inside, posing a threat to the structural integrity and durability of the wall. Wall cracks and structural instability caused by problems with the support system may require additional repair and reinforcement work, which not only prolongs the construction period but also increases the construction cost. Therefore, a concrete wall anti-cracking structure is needed to solve the above problems. Content of the Utility Model

[0003] The utility model provides a concrete wall anti-cracking structure that improves the stability of concrete formwork support, construction efficiency, and concrete quality to solve the deficiencies of the prior art.

[0004] To achieve the above object, the utility model first proposes a concrete wall anti-cracking structure, which includes two formwork bodies and a cover plate. The two formwork bodies are arranged in parallel, and the tops of the two formwork bodies are connected by the cover plate. The cover plate and the two formwork bodies enclose a pouring space. A trapezoidal groove is formed on one side of the formwork body, and a trapezoidal insert block matching the trapezoidal groove is fixedly arranged on the other side. A support assembly for supporting the vertically arranged formwork body is arranged on the outer side surface of the formwork body.

[0005] The support assembly includes two vertically arranged vertical grooves symmetrically distributed left and right on the outer side wall of the formwork body. A telescopic rod matching the length of the vertical groove is installed in the vertical groove. The telescopic rod includes a square rod and a screw rod. An internal thread hole matching the screw rod is arranged along the length direction in the square rod. The top end of the square rod is hinged in the vertical groove, and the bottom end of the square rod is rotationally assembled with an internal thread knob. The internal thread knob is coaxially arranged with the internal thread hole, and the thread in the internal thread knob matches the thread of the screw rod. One end of the screw rod is threadedly installed in the internal thread hole, and the other end extends out of the thread hole of the internal thread knob to form a support end. The screw rod is in threaded connection with the internal thread knob. The bottom of the support end of the screw rod is hinged with a rotating seat, and the rotating seat is rotationally assembled on the support plate.

[0006] In this embodiment, a heat-insulating layer is also provided inside the formwork body itself, so as to insulate the poured concrete and prevent the concrete from cracking.

[0007] In this embodiment, a connecting groove is provided on the outer surface of the template body, between the two vertical grooves, and at the position of the internally threaded knob. Sprockets are coaxially fixed outside the two internally threaded knobs. The sprockets of the two internally threaded knobs are connected to each other through a chain to achieve linkage of the two internally threaded knobs.

[0008] In this embodiment, a rotating knob for facilitating the rotation of the internally threaded knob is coaxially fixed to the lower side of the internally threaded knob.

[0009] In the present embodiment, a long groove connected to the inverted trapezoidal groove is provided on the outer side surface of the template body near the middle of the inverted trapezoidal groove, a locking groove is provided on the trapezoidal plug block of the template body at the position of the long groove, a flap is rotatably installed in the long groove, the flap is arranged vertically and matches the size of the long groove, a rotating shaft arranged along the vertical direction is provided on the side of the flap close to the trapezoidal plug block, the flap is rotatably installed in the long groove through the rotating shaft, and a locking tongue matching the locking groove is fixed on the other side of the flap, on the side facing the inverted trapezoidal groove; when multiple template bodies are connected, the flap rotates around the rotating shaft to drive the locking tongue to insert into the lock groove or move away from the lock groove; the outer side surface of the template body is also provided with a driving member that drives the flap to rotate around the rotating shaft.

[0010] In this embodiment, the driving member includes a vertical plate fixed on the outer wall of the template body and arranged in the vertical direction, the vertical plate is arranged perpendicular to the template body, a plurality of guide rods are fixed to the vertical plate on the side facing the flap, the guide rods are arranged perpendicular to the vertical plate, a toggle plate is slidably installed on the plurality of guide rods, the toggle plate is arranged parallel to the vertical plate, a plurality of vertically arranged springs are fixed between the toggle plate and the vertical plate, a plurality of vertically arranged connecting rods are hinged on the side of the toggle plate facing the flap, the connecting rods are arranged parallel to the guide rods, and the other end of the connecting rods is hinged on the side of the flap close to the lock tongue.

[0011] Due to the adoption of the above structure, the utility model has the following advantages:

[0012] 1. When multiple template bodies are connected, it is only necessary to plug the inverted trapezoidal grooves and trapezoidal plug-ins of adjacent template bodies into each other, thereby improving the connection efficiency of the template body and reducing the labor intensity of the operator; when the template body needs to be supported, the operator pulls the telescopic rod to disengage the telescopic rod from the vertical groove. After the telescopic rod is rotated to a suitable angle, the operator rotates the internal threaded knob. The rotation of the internal threaded knob drives the screw rod to gradually extend from the square rod, and the screw rod simultaneously drives the support plate to move downward until the support plate abuts against the ground. The above method can quickly support the template body and the operation is more convenient.

[0013] 2. The sprockets of the two internally threaded knobs are connected to each other through a chain to realize the linkage of the two internally threaded knobs. In this way, the two telescopic rods can be synchronously extended and retracted by simply turning the internally threaded knob on one side, thereby synchronously adjusting the extension length of the two screw rods. Of course, a motor can also be installed on the square rod and connected to the internally threaded knob through a transmission device to realize the rotation of the internally threaded knob.

[0014] 3. This device drives the flap to rotate through the driving member to achieve locking after the adjacent formwork bodies are connected. On the one hand, the vertical movement of the adjacent formwork bodies can be limited. On the other hand, by confirming the connection between the lock tongue and the lock groove, it can be ensured that the adjacent formwork bodies are in the same horizontal plane, thereby ensuring the quality of poured concrete. Through the driving member, when disassembling and assembling, the operator only needs to push the toggle plate away from the flap to compress the spring. The toggle plate simultaneously drives the connecting rod to move, so that the connecting rod pulls the flap to rotate around the rotating shaft. At this time, the lock tongue is disengaged from the lock groove of the inverted trapezoidal groove, thereby facilitating the disassembly and assembly of the adjacent formwork bodies.

[0015] To sum up, the utility model extends the screw inside the internal threaded hole by rotating the internal threaded knobs on both sides, and the screw drives the support plate to descend, thereby improving the stable supporting force of the formwork body through the support plate. During the pouring process, the stability of the formwork body is ensured, and the quality of the poured concrete is ensured. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0026] As Figure 1-7 shown, a concrete wall anti-cracking structure of the present invention includes two formwork bodies 1 and a cover plate 10. The two formwork bodies 1 are arranged in parallel, and the tops of the two formwork bodies 1 are connected by the cover plate 10. The cover plate 10 and the two formwork bodies 1 enclose a pouring space. Further, a heat preservation layer 32 is also provided inside the formwork body 1 itself; the heat preservation layer 32 is used to keep the poured concrete warm and avoid cracking of the concrete. An inverted trapezoidal groove 11 is formed on one side of the concrete formwork body 1, and a trapezoidal insert block 12 matching the inverted trapezoidal groove 11 is fixedly provided on the other side. A support assembly for supporting the vertically arranged formwork body 1 is provided on the outer side surface of the formwork body 1; as Figure 6 shown, the inverted trapezoidal groove 11 is a groove with a smaller notch than the bottom surface.

[0027] The support assembly includes two vertically arranged vertical grooves 13 that are symmetrically distributed left and right on the outer sidewall of the template body 1. An expansion rod matching the length of the vertical groove 13 is installed in the vertical groove 13. The expansion rod includes a square rod 14 and a screw rod 16. An internal threaded hole 15 matching the screw rod 16 is provided in the square rod 14 along the length direction. The top end of the square rod 14 is hinged in the vertical groove 13, and an internal threaded knob 17 is rotatably assembled at the bottom of the square rod 14. The internal threaded knob 17 is coaxially arranged with the internal threaded hole 15, and the thread in the internal threaded knob 17 matches the thread of the screw rod 16. One end of the screw rod 16 is threadedly installed in the internal threaded hole 15, and the other end extends out from the threaded hole of the internal threaded knob 17 to form a support end. The screw rod 16 is threadedly connected to the internal threaded knob 17, and the bottom of the support end of the screw rod 16 is hinged to a rotating seat. The rotating seat is rotatably assembled on the support plate 18;

[0028] When multiple template bodies 1 are connected, it is only necessary to insert the inverted trapezoidal grooves 11 and trapezoidal inserts 12 of adjacent template bodies 1 into each other, thereby improving the connection efficiency of the template body 1 and reducing the labor intensity of the operator; when the template body 1 needs to be supported, the operator pulls the expansion rod so that the expansion rod disengages from the vertical groove 13. After the expansion rod rotates to a suitable angle, the operator then rotates the internal threaded knob 17. By rotating the internal threaded knob 17, the screw rod 16 gradually extends out of the square rod 14. The screw rod 16 synchronously drives the support plate 18 to move downward until the support plate 18 abuts against the ground. By adopting the above method, the template body 1 can be quickly supported, and the operation is more convenient;

[0029] As Figures 1 to 4 shown, a connection groove is provided on the outer side surface of the template body 1, between the two vertical grooves 13, and at the position where the internal threaded knobs 17 are located. Two sprockets 21 are coaxially fixed outside the two internal threaded knobs 17. The sprockets 21 of the two internal threaded knobs 17 are connected to each other through a chain 20 to achieve the linkage of the two internal threaded knobs. Two rotary knobs 31 for conveniently rotating the internal threaded knobs 17 are coaxially fixed below the two internal threaded knobs 17; in this way, only by rotating one of the internal threaded knobs 17, the synchronous expansion and contraction of the two expansion rods can be achieved, so that the extended lengths of the two screw rods 14 can be synchronously adjusted. Of course, a motor can also be installed on the square rod 14 and connected to the internal threaded knob 17 through a transmission device to achieve the rotation of the internal threaded knob 17.

[0030] As Figure 4 、 5As shown in the figure, on the outer side of the template body 1, a long groove communicating with the inverted trapezoidal groove 11 is provided at a position near the middle of the inverted trapezoidal groove 11. On the trapezoidal insert block 12 of the template body 1, a locking groove is provided at the position of the long groove. A flap 22 is rotatably assembled in the long groove. The flap 22 is vertically arranged and matches the size of the long groove. A rotating shaft is provided on one side of the flap close to the trapezoidal insert block 12 in the vertical direction. The flap is rotatably assembled in the long groove through the rotating shaft. On the other side of the flap, a locking tongue matching the locking groove is fixed on the surface facing the inside of the inverted trapezoidal groove 11. When multiple template bodies 1 are connected, the flap rotates around the rotating shaft to drive the locking tongue to insert into or away from the locking groove. A driving member for driving the flap to rotate around the rotating shaft is also provided on the outer side of the template body 1.

[0031] The driving member includes a vertical plate 23 fixed on the outer side wall of the template body 1 and vertically arranged. The vertical plate 23 is perpendicularly arranged with the template body 1. On the side of the vertical plate 23 facing the flap 22, multiple guide rods are fixed. The guide rods are perpendicularly arranged with the vertical plate 23. A toggle plate 24 is slidably installed on the multiple guide rods. The toggle plate 24 is parallel to the vertical plate 23. Multiple springs 25 arranged vertically are fixed between the toggle plate 24 and the vertical plate 23. On the side of the toggle plate 24 facing the flap 22, multiple connecting rods 26 arranged vertically are hinged. The connecting rods 26 are parallel to the guide rods. The other end of the connecting rod 26 is hinged on the side of the flap close to the locking tongue.

[0032] In the locked state, the toggle plate 24 moves away from the vertical plate 23 under the elastic action of the spring 25. The toggle plate 24 pushes the connecting rod 26 to make the locking tongue on the flap 22 snap into the locking groove of the inverted trapezoidal groove 11, so as to limit the adjacent template body 1. On the one hand, it can limit the vertical movement of the adjacent template body 1. On the other hand, by confirming the connection between the locking tongue and the locking groove, it can ensure that the adjacent template bodies 1 are all on the same horizontal plane, ensuring the quality of the cast concrete.

[0033] In the disassembled state, the operator pushes the toggle plate 24 in the direction away from the flap 22, compressing the spring 25. The toggle plate 24 synchronously drives the connecting rod 26 to move, so that the connecting rod 26 pulls the flap 22 to rotate around the rotating shaft, and the locking tongue disengages from the locking groove of the inverted trapezoidal groove 11, facilitating the disassembly and assembly of the adjacent template bodies.

[0034] The above is only the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
